Editing all buildings and all features.

If you want to edit anything on hq use targa files and photoshop. The file names would be as follows:

army_hq_lid this one is the flag the sandbags and the lid of the canarmy_hq_tower_ps2 This one is the radio tower on hqarmy_hq_pistons this is the pistons on the side of the super hqarmy_hq_main this is the area where you would place the soda name and make a design

You should download the Rul3 map pack because it has all those files and you will be able to have an easier basis to work on them off of.
